Greddy emanage piggyback fuel controller. Comes with ALL harnesses, Support tool software, Support tool cable (the Greddy one, not a clone), map sensor, original manuals, boxes, etc. This is blue box upgraded to gold specs. I will include the latest software and firmware to run as a gold emanage, and a nice 3rd party logger. I've had no problems with the unit, I've just outgrown it and I'm moving on to something else. I will trade for a set of low impedance top feed injectors 680cc's or larger. $275 obo.
